Braking
&Braking tips
WARNING
Never rest your foot on the brake
pedal while driving. This can cause
dangerous overheating of the
brakes and needless wear on the
brake pads and linings.
! When the brakes get wet
When driving in rain or after washing the
vehicle, the brakes may get wet. As a
result, brake stopping distance will be
longer. To dry the brakes, drive the vehicle
at a safe speed while lightly depressing
the brake pedal to heat up the brakes.
! Use of engine braking
Remember to make use of engine braking
in addition to foot braking. When descend-
ing a grade, if only the foot brake is used,
the brakes may start working improperly
because of brake fluid overheating,
caused by overheated brake pads. To
help prevent this, shift into a lower gear to
get stronger engine braking.
! Braking when a tire is punctured
Do not depress the brake pedal suddenly
when a tire is punctured. This could cause a loss of control of the vehicle. Keep
driving straight ahead while gradually
reducing speed. Then slowly pull off the
road to a safe location.&
Brake system
! Two separate circuits
Your vehicle has two separate circuit
brake systems. Each circuit works diag-
onally across the vehicle. If one circuit of
the brake system should fail, the other half
of the system still works. If one circuit fails,
the brake pedal will go down much closer
to the floor than usual and you will need to
press it down much harder. And a much
longer distance will be needed to stop the
vehicle.
! Brake booster
The brake booster uses engine manifold
vacuum to assist braking force. Do not
turn the ignition switch to the “LOCK”/
“OFF ”position while driving because that
will turn off the brake booster, resulting in
poor braking power.
The brakes will continue to work even
when the brake booster completely stops
functioning. If this happens, however, you
will have to depress the pedal much
harder than normal and the braking dis-
tance will increase. !
Brake assist system
WARNING
Do not be overconfident about the
brake assist. It is not a system that
brings more braking ability to the
vehicle beyond its braking capabil-
ity. Always use the utmost care
when driving regarding vehicle
speed and safe distance.
CAUTION
When you need to brake suddenly,
continue depressing the brake pedal
strongly to bring the effect of the
brake assist.
Brake assist is a driver assistance system.
It assists the brake power when the driver
cannot depress the brake pedal strongly
and the brake power is insufficient.
Brake assist generates the brake power
according to the speed at which the driver
depresses the brake pedal.
NOTE
When you depress the brake pedal
strongly or suddenly, the following
phenomena occur. However, even
though these occur, they do not indi-

Starting and operating/ABS (Anti–lock Brake System)
cate any malfunctions, and the brake
assist system is operating properly.
. You might feel that the brake pedal
is applied by lighter force and gener-
ates a greater braking force.
. You might hear an ABS operating
noise from the engine compartment.
& Disc brake pad wear warning
indicators
The disc brake pad wear warning indica-
tors on the disc brakes give a warning
noise when the brake pads are worn.
If a squeaking or scraping noise is heard
from the disc brakes while braking, im-
mediately have your vehicle checked by
your SUBARU dealer.
ABS (Anti-lock Brake Sys-
tem)
The ABS prevents the lock-up of wheels
which may occur during sudden braking or
braking on slippery road surfaces. This
helps prevent the loss of steering control
and directional stability caused by wheel
lock-up.
When the ABS is operating, you may hear
a chattering noise or feel a slight vibration
in the brake pedal. This is normal when
the ABS operates.
The ABS will not operate when the vehicle
speed is below approximately 6 mph (10
km/h).
WARNING
Always use the utmost care in
driving –overconfidence because
you are driving a vehicle with the
ABS could easily lead to a serious
accident.
CAUTION
. The ABS does not always de-
crease stopping distance. You
should always maintain a safe following distance from other
vehicles.
. When driving on badly surfaced
roads, gravel roads, icy roads, or
over deep newly fallen snow,
stopping distances may be long-
er for a vehicle with the ABS than
one without. When driving under
these conditions, therefore, re-
duce your speed and leave ample
distance from other vehicles.
. When tire chains are installed,
stopping distances may be long-
er for a vehicle with the ABS than
one without. Be sure to reduce
your speed and maintain a safe
distance from the vehicle in front.
. When you feel the ABS operating,
you should maintain constant
brake pedal pressure. Do not
pump the brake pedal since
doing so may defeat the opera-
tion of the ABS.
& ABS self-check
Just after the vehicle is started, you may
feel on the brake pedal a vibration similar
to when the ABS operates, and you may
also hear the sound of the ABS working
from the engine compartment. This is

Starting and operating/Vehicle Dynamics Control system
system warning light and ABS warning
light illuminate simultaneously.
The EBD system may be malfunctioning if
the brake system warning light and ABS
warning light illuminate simultaneously
during driving.
Even if the EBD system malfunctions, the
conventional braking system will still func-
tion. However, the rear wheels will be
more prone to locking when the brakes
are applied harder than usual and the
vehicle’s motion may therefore become
somewhat harder to control.
If the brake system warning light and ABS
warning light illuminate simultaneously,
take the following steps.
1. Stop the vehicle in the nearest safe,
flat location.
2. Apply the parking brake and turn off
the engine.
3. Restart the engine.
4. Release the parking brake.
Even if both warning lights turn off:
The EBD system may be malfunctioning.
Drive carefully to the nearest SUBARU
dealer and have the system inspected.
If both warning lights illuminate again
and remain illuminated after restarting
the engine:
1. Turn off the engine again. 2. Apply the parking brake.
3. Check the brake fluid level. For details
about checking the brake fluid level, refer
to
“Checking the fluid level ”F 11-16.
. If the brake fluid level is not below the
“MIN ”mark, the EBD system may be
malfunctioning. Drive carefully to the
nearest SUBARU dealer and have the
system inspected.
. If the brake fluid level is below the
“MIN ”mark, DO NOT drive the vehicle.
Instead, have the vehicle towed to the
nearest SUBARU dealer for repair.
WARNING
. Driving with the brake system
warning light illuminated is dan-
gerous. This indicates your brake
system may not be working
properly. If the light remains
illuminated, have the brakes in-
spected by a SUBARU dealer
immediately.
. If at all in doubt about whether
the brakes are operating prop-
erly, do not drive the vehicle.
Have your vehicle towed to the
nearest SUBARU dealer for re-
pair.
Vehicle Dynamics Control
system
& Safety precautions
WARNING
Always use the utmost care in
driving –overconfidence because
you are driving a vehicle with the
Vehicle Dynamics Control system
could easily lead to a serious acci-
dent.
CAUTION
. Even if your vehicle is equipped
with Vehicle Dynamics Control
system, winter tires should be
used when driving on snow-cov-
ered or icy roads; in addition,
vehicle speed should be reduced
considerably. Simply having a
Vehicle Dynamics Control sys-
tem does not guarantee that the
vehicle will be able to avoid
accidents in any situation.
. Activation of the Vehicle Dy-
namics Control system is an
indication that the road being
travelled on has a slippery sur-

Vehicle Dynamics Control OFF indicator
light (type B)
When the switch is pressed during engine
operation, the Vehicle Dynamics Control
OFF indicator light“
”on the combination
meter illuminates. The Vehicle Dynamics
Control system will be deactivated and the
vehicle will behave like a model not
equipped with the Vehicle Dynamics Con-
trol system. When the switch is pressed
again to reactivate the Vehicle Dynamics
Control system, the Vehicle Dynamics
Control OFF indicator light turns off.
With the Vehicle Dynamics Control system
deactivated, traction and stability en-
hancement offered by Vehicle Dynamics
Control system is unavailable. Therefore
you should not deactivate the Vehicle
Dynamics Control system except under above-mentioned situations.
NOTE
.
When the switch has been pressed
to deactivate the Vehicle Dynamics
Control system, the Vehicle Dynamics
Control system automatically reacti-
vates itself the next time the ignition
switch is turned to the “LOCK”/“OFF ”
position and the engine is restarted.
. If the switch is held down for 30
seconds or longer, the indicator light
turns off, the Vehicle Dynamics Control
system is activated, and the system
ignores any further pressing of the
switch. To make the switch usable
again, turn the ignition switch to the
“LOCK ”/“OFF ”position and restart the
engine.
. When the switch is pressed to
deactivate the Vehicle Dynamics Con-
trol system, the vehicle ’s running per-
formance is comparable with that of a
vehicle that does not have a Vehicle
Dynamics Control system. Do not de-
activate the Vehicle Dynamics Control
system except when absolutely neces-
sary.
. Even when the Vehicle Dynamics
Control system is deactivated, compo-
nents of the brake control system may
still activate. When the brake control
system is activated, the Vehicle Dy- namics Control operation indicator
light flashes.

WARNING
.Never leave unattended children
or pets in the vehicle. They could
accidentally injure themselves or
others through inadvertent op-
eration of the vehicle. Also, on
hot or sunny days, the tempera-
ture in a closed vehicle could
quickly become high enough to
cause severe or possibly fatal
injuries to people.
. Do not park the vehicle over
flammable materials such as dry
grass, waste paper or rags, as
they may burn easily if they come
near hot engine or exhaust sys-
tem parts.
. Be sure to stop the engine if you
take a nap in the vehicle. If
engine exhaust gas enters the
passenger compartment, occu-
pants in the vehicle could die
from carbon monoxide (CO) con-
tained in the exhaust gas.
CAUTION
If your vehicle has a front under-
spoiler and rear underspoiler (both
optional), pay attention to blocks and other obstructions on the
ground when parking. The under-
spoilers could be damaged by con-
tact with them.
Hill start assist system
WARNING
.
The Hill start assist system is a
device only for helping the driver
to START the vehicle on an uphill
grade. To prevent accidents
when the vehicle is parked on a
slope, be sure to firmly set the
parking brake. When setting the
parking brake, make sure that the
vehicle remains stationary when
the clutch pedal (MT models) and
brake pedal (both MT and CVT
models) are released.
. Do not turn the ignition switch to
the “LOCK ”/“OFF ”position while
the Hill start assist system is
operating. The Hill start assist
system will be deactivated and
may lead to an accident.
The Hill start assist system is a device to
make the following vehicle operations
easier.

Starting and operating/Hill start assist system
1) Starting forward facing uphill
2) Starting backward facing downhill
A) Brake pedal (both MT models and CVTmodels)
B) Clutch pedal (MT models only)
In both these cases, the Hill start assist
system operates under the following con- ditions.
.
when the clutch pedal is depressed
while the brake pedal is also depressed
(MT models)
. when the vehicle has stopped with the
brake pedal depressed (CVT models)
Braking power is maintained temporarily
(for approximately 2 seconds) by the Hill
start assist system after the brake pedal is
released. The driver is therefore able to
start the vehicle in the same way as on a
level grade, just using the clutch pedal
(MT models only) and accelerator pedal
(all models).
If the braking power of the Hill start assist
system is insufficient after the brake pedal
is released, apply more braking power by
depressing the brake pedal again.
The Hill start assist system may not
operate on slight grades. Also, the Hill
start assist system does not operate in the
following cases.
. when starting backward facing uphill
. when starting forward facing downhill
. while the parking brake is applied
. while the ignition switch is in the “ACC”
or “LOCK ”/“OFF ”position
. while the Hill start assist warning light/

illuminated
When using the Hill start assist system, a
braking effect may be felt even after the
brake pedal has been released. However,
for MT models, this braking effect should
disappear once the clutch pedal is re-
leased.
NOTE
A slight jolt may be felt when the
vehicle begins to move forward after
being reversed.
&To activate/deactivate the Hill
start assist system
CAUTION
While the Hill start assist system is
deactivated, when starting on an
uphill grade, braking power is not
maintained if the brake pedal is
released. Start on an uphill grade
